If you need to create an A record that points at a IP in a range that does not belong to you, for example and AWS IP; you need to first create a Network Association so that non-yours IP Address or IP Range can be referred to by a DNS domain we hold the forwards for. Note that the reverse DNS will be resolved by whomever owns the IP (or someone they have delegated to), in this example AWS.<\/p>\n\n\n\n

1. Open IPAM.<\/p>\n\n\n\n

2. Create a network range to represent the range of external non-yours Internet routable IPs within a CIDR range, or if you already have one, you’ll create a record within.<\/p>\n\n\n\n

3. Click “Create IPv4 Network” (yes, even if its just a single IP).<\/p>\n\n\n\n

4. Click “Manual”<\/p>\n\n\n\n

5. Enter the details, for example the below:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

6. Click “Save & Close”<\/p>\n\n\n\n

7. Now, edit the IPAM network you just created.<\/p>\n\n\n\n

8. Click “General”\u2192”Advanced” and add the DNS Zone Association (in this example the domain.net DNS zone), you’ll need to click “Override” first.<\/p>\n\n\n\n

10. Click “Save & Close”<\/p>\n\n\n\n

You have now created an association of that external (non-yours) IP (or IP Range) to the DNS zone, and you can now create your A record as normal, ensuring you don’t attempt to create the PTR, i.e. don’t tick the “create associated PTR record” when creating.<\/p>\n","protected":false},"excerpt":{"rendered":"
